Molex is the power plug type used for hard drives and CD drives in older PATA-type PC's. Berg is the same, except used for floppy drives.
The white one that fits. :) Here's <a href="http://www.nuggetlab.com/comptia_files/equipmentperif_Molex%20style%20power%20connector.jpg">a picture for you</a> -- They're not always white, sometime black.
The power connectors used by both 5.25-inch and 3.5-inch floppy drives are 4-pin connectors. The larger connector--used by 5.25-inch drives--is called a Molex or peripheral cable. This type of cable is also used by IDE/ATA hard drives and optical drives. The smaller 4-pin cable used by 3.5-inch floppy drives is generally called a floppy power cable.
There are two kinds in common use:Molex - an older standard, but still commonSATA - Serial ATA, a newer standardSee the related links for pictures.

Almost all connectors are designed as such. PATA and SATA cables are usually keyed so that they can only be connected in one direction. SCSI connectors are shaped in a way that makes it impossible to establish a complete connection in the wrong direction.
